In this talk I first present an overview of Standard Model predictions for CP violation in the neutral B-meson sector. Then, I present a status report from the <img src="http:/img/fbpe/bjp/v30n2/sbgtra.gif" border="0"> experiment at the Stanford Linear Accelerator Center which has been designed especially to measure time-dependent asymmetries whose interpretation in the Standard Model is directly related to the parameters of the Cabibbo-Kobayashi-Maskawa mixing matrix.
